using ssh

[moonhkt]

Hi All

Why using ssh command , already return Hi then hostname ?

ssh remote hostname

output as below
Hi <-- Already return this line
myhostname

moonhkt

I would assume it's the remote host's motd. Mine says:

Go away.

It could also be something in the shell profiles on the remote side
printing something to the screen.

I like to "touch ~/.hushlogin" to quiet a LOT of that stuff down.

(I execute a lot of remote commands ssh remote command and don't want
all the motd / banner type stuff cluttering my terminal.)

Isn't motd only shown on interactive logins? ssh with a command on the
command line isn't interactive.

I was thinking the same thing, but .profile should only be loaded on
interactive logins.

I hear you.

I don't remember the specifics. It may have been in place before I did
a LOT of "ssh host remote-command" type activity and / or it may have
been motd / issue related.

However, .cshrc is executed for every shell and .bashrc also for
remote logins. A good number of people who report mysterious
problems on the openssh-unix-dev mailing list have some command
that produces output in .bashrc.

Yep, I've been bitten by that one before.

Fortunately I was able to log in interactively and fix things. Though I
did result to uuencoding files for a few minutes to transfer files and
fix things.

find "hi" on this file .bashrc

On normal Linux systems at least, whether or not motd is shown
ultimately depends on the PAM configuration. On my current desktop the
relevant line is hidden beneath 2 levels of includes:

matica!5 ~$ fgrep motd /etc/pam.d/system-login
session optional pam_motd.so motd=/etc/motd

matica!6 ~$ fgrep system-login /etc/pam.d/*
/etc/pam.d/system-local-login:auth include system-login
/etc/pam.d/system-local-login:account include system-login
/etc/pam.d/system-local-login:password include system-login
/etc/pam.d/system-local-login:session include system-login
/etc/pam.d/system-remote-login:auth include system-login
/etc/pam.d/system-remote-login:account include system-login
/etc/pam.d/system-remote-login:password include system-login
/etc/pam.d/system-remote-login:session include system-login

matica!7 ~$ fgrep system-local-login /etc/pam.d/*
/etc/pam.d/login:auth include system-local-login
/etc/pam.d/login:account include system-local-login
/etc/pam.d/login:password include system-local-login
/etc/pam.d/login:session include system-local-login
/etc/pam.d/runuser-l:auth include system-local-login
/etc/pam.d/runuser-l:account include system-local-login
/etc/pam.d/runuser-l:password include system-local-login
/etc/pam.d/runuser-l:session include system-local-login
